Installing Adobe Air on 64bit Linux

So, I recently installed Ubuntu 9.10 64bit on my pc. And, when I went to install Adobe Air so that I could test DarkRoomX it didn’t work. Or, rather the installer completed but it didn’t actually work. So, I had to dig up some instructions for getting it to work (you need to manually install some 32bit libs). Here’s the link if anyone else is trying to do the same thing:

The unfortunate side effect is that it completely hosed flash on my system. I am running a fairly fresh image of ubuntu 9.10 (64-bit) and all attempts to remove and reinstall the flash plugins since have failed.

From synaptic, trying to install the packages { flashplugin-installer, flashplugin-nonfree, nspluginwrapper } now always fail towards the end (I’ve tried completely removing them and reinstalling them, to no avail). Excerpt from the synaptic details pane : :
